Code blocks

Markdown fenced code blocks are styled automatically. Their toolbar identifies the language and includes a Copy button when the Clipboard API is available. The button shows a visible success or failure state while a polite live region announces the same result to assistive technology.

The toolbar prints a readable label for the detected language, so bash reads Shell and text reads Text instead of Zola's internal syntax name.

```toml
theme = "devlab-theme"
compile_sass = true
```

theme = "devlab-theme"
compile_sass = true

Add name= to give a block a filename or path caption. DevLab renders it as the block title and shows the language beside it:

```bash,name=build.sh,linenos
make -j"$(nproc)"
```

1make -j"$(nproc)"

The value travels in Zola's native data-name attribute, so it is never inserted into the copied text. Use a single path-like token without spaces, because Zola parses the fence info string as a comma-separated attribute list.

Add linenos for line numbers and hl_lines for individual lines or ranges:

```rust,linenos,hl_lines=2
fn main() {
    println!("this line is highlighted");
    println!("this one is not");
}
```

1fn main() {
2    println!("this line is highlighted");
3    println!("this one is not");
4}

These annotations are native Zola highlighting features. DevLab styles them and strips line numbers when copying.
